/proc/net/ip_masquerade has similar problems, as does
/proc/net/ip_tables_names (although you will probably
never have enough table names for that one to occur).
I posted a patch for these a while ago:

thanks for pointing this out.  I simply missed it.  Please try pushing
this again as soon as you think something was missed.

I'll put it in the pending repository of pom now.
